Design of an integrated energy supply system based on photovoltaic-thermal-air-cooled-heat-pump for air conditioning of plant factory
This work addresses the limitations of typical plant factories,such as their reliance on single energy sources,low profitabili-ty,and limited sustainability.An air conditioning system based on combined solar photovoltaic-thermal-air-cooled-heat-pump for plant factory is proposed.Air-cooled heat pump and solar photothermal is utilized for cooling and heating of the plant factory,respectively.And solar photovoltaic covers the factory's electricity consumption partially.Based on the cooling and heating load of the plant factory,an air-cooled heat pump with 8.5 kW heating capacity and 7.2 kW cooling capacity is selected.The required number of photovoltaic-thermal(PV/T)modules is determined by calculating the collection area of the PV/T collector.The output power of PV/T modules and the percentage of plant factory power consumption that the PV/T modules can cover were calculated.Additionally,the economic vi-ability and carbon reduction potential of the plant factory system equipped with PV/T modules is analyzed in this work.
